how many hcl molecules do you need to balance this equation mg hcl mgcl2 + h2 HELLP PL DIS IS AFINAL EXAM PLLZ HEP

g + 2HCl ——-> MgCl2 + H2

To balance an equation the number of atoms on the LHS of an equation must equal the number of atoms on the RHS of an equation. (This is known as the Law of Conservation of Matter.) To balance any equation, the FORMULA OF ANY SUBSTANCE INVOLVED MUST NEVER BE ALTERED. Numbers can only be placed in front of any substance.

Hence, in the above example, a 2 is placed in front of HCl making the number of hydrogens = 2 and the number of chlorines = 2 on the LHS. This matches the number of hydrogens = 2 and number of chlorines = 2 on the RHS.

Hope this helps~
